And one question about the LM3886T, non-isolated, can I put it on the heatsink without isolation as long as the heatsink isn't connected to something, or do I short it if I do so?

That resistor is a 10ohm/3W which has 10 turns of 1mm copper wire. My boards are using the non insulated but my case is made out of wood. If the heatsink doesn't touch any other connected metallic part, it's fine.

For those who use press'n'peel: don't print the view in mirror, print it exactly how it's in EAGLE. Leave only pads, bottom and dimension in view then at print options choose "Solid" and "Black"

Okay!
Then I'm good to go! Hopefully the amps are done pretty soon and then I'll show them here!
